CVE-2024-8594 is a heap-based buffer overflow vulnerability identified in Autodesk AutoCAD, specifically within the libodxdll.dll library responsible for parsing MODEL files. This vulnerability arises when a maliciously crafted MODEL file is processed by AutoCAD versions 2022 through 2025. The flaw allows an attacker to overflow a heap buffer, which can lead to several critical consequences: causing the application to crash (denial of service), unauthorized disclosure of sensitive data, or execution of arbitrary code within the context of the AutoCAD process. Exploitation involves supplying a specially crafted MODEL file to the vulnerable AutoCAD software, which does not require prior authentication or elevated privileges beyond those of the user running the application. The vulnerability is classified under CWE-122, indicating a heap-based buffer overflow, a common and dangerous class of memory corruption bugs. As of the publication date, no known exploits have been observed in the wild, and Autodesk has not yet released official patches. The vulnerability was reserved in early September 2024 and publicly disclosed at the end of October 2024. Given the nature of AutoCAD as a widely used CAD software in engineering, architecture, and manufacturing sectors, this vulnerability poses a significant risk to organizations relying on these industries. The attack vector is primarily through opening or importing malicious MODEL files, which could be delivered via email, shared network drives, or compromised repositories. Successful exploitation could allow attackers to gain code execution capabilities, potentially leading to further network compromise or data theft within affected environments.

For European organizations, the impact of CVE-2024-8594 can be substantial, especially for those in sectors heavily reliant on AutoCAD for design and engineering workflows, such as automotive, aerospace, construction, and manufacturing. Exploitation could lead to operational disruptions due to application crashes, loss or theft of intellectual property embedded in design files, and potential lateral movement within corporate networks if arbitrary code execution is achieved. This could compromise the confidentiality and integrity of sensitive design data, which is often critical for competitive advantage and regulatory compliance. Additionally, availability may be affected if AutoCAD becomes unstable or unusable due to exploitation attempts. The risk is heightened in environments where AutoCAD is used with elevated privileges or integrated into broader enterprise systems. Given the lack of known exploits in the wild, the immediate threat level is moderate; however, the potential for future exploitation necessitates proactive measures. European organizations with collaborative design workflows involving external partners may also face increased exposure due to the possibility of receiving malicious MODEL files from untrusted sources.

1. Implement strict file validation and sandboxing: Use application whitelisting and sandbox environments to open MODEL files from untrusted sources, minimizing risk exposure. 2. Restrict AutoCAD usage to least privilege: Ensure AutoCAD runs with minimal user privileges to limit the impact of potential code execution. 3. Employ network segmentation: Isolate systems running AutoCAD from critical infrastructure to prevent lateral movement if exploitation occurs. 4. Monitor and filter incoming files: Deploy advanced email and network security solutions to detect and block suspicious MODEL files or attachments. 5. Maintain rigorous patch management: Monitor Autodesk advisories closely and apply patches immediately upon release. 6. Conduct user training: Educate users on the risks of opening files from unknown or untrusted sources, emphasizing safe handling of design files. 7. Use endpoint detection and response (EDR) tools: Implement EDR solutions capable of detecting anomalous behaviors indicative of exploitation attempts within AutoCAD processes. 8. Regularly back up design data: Ensure backups are maintained offline or in immutable storage to recover from potential data corruption or ransomware attacks leveraging this vulnerability.
